WDR-120-24 Industrial DIN Rail Power Supply (24V 5A 120W, 200-500VAC Wide Input)

Architectural Overview & Industrial Grid Resilience
The WDR-120-24 is an ultra-wide input industrial DIN-rail switch-mode power supply designed for critical process control, industrial robotics, and automation infrastructure. Engineered to handle single-phase or two-phase phase-to-phase grids from 200VAC to 500VAC (180 to 550VAC operational), it eliminates power instability caused by grid transients, multi-phase line imbalances, and unexpected industrial line sags.

Precision Power Conversion & Efficiency
Delivering an ultra-clean 24V DC output at up to 5A (120W rated), the power supply leverages high-efficiency synchronous switching topology to achieve up to 91% conversion efficiency. This optimized thermal efficiency reduces parasitic cabinet heating, extends MTBF life expectancy, and guarantees full-load stability with low output ripple and noise under fluctuating automation load profiles.

Compact Form Factor & Passive Thermal Design
Housed in an ultra-slim 40mm metal chassis engineered for TS-35/7.5 and TS-35/15 DIN-rail mounting, the unit maximizes rail space in tightly packed enclosures. The design relies entirely on free air convection cooling across an extended operational range of -25°C to +70°C, eliminating failure-prone cooling fans and preventing particulate ingestion.

Comprehensive Fault Protection & Telemetry
Integrated electrical safety layers include continuous short-circuit protection, constant-current overload protection, over-voltage clamping, and multi-stage thermal shutdown with automatic recovery. A built-in DC-OK dry relay contact offers immediate telemetry status to supervisory PLCs and edge IoT gateways for automated power diagnostics.

Deployment Applications & System Integration
Ideal for factory automation, machine tool engineering, distributed motor control panels, building infrastructure, and IIoT communication cabinets where standard 115V/230V feeds are unavailable or subject to phase failure risks across industrial 400V/480V networks.
